FRANK D. MACK, OF CHICAGO, ILLINOIS.

PERFORATOR FOR AUTOMATIC TELEGRAPHING.

SPECIFICATION forming part of Letters Patent No. 439,164, dated October28, 1890.

Application filed July 13, 1889. Serial No. 317,485. (No model.)

To all whom it may concern: Be it known that I, FRANK D. MACK, resid-1ng at Chicago, in the county of Cook and State of Illinois, and acitizen of the United States,

have invented a new and useful Improvement in Perforators for AutomaticTelegraphing, of which the following is a specification, reference beinghad to the accompanying drawings, in which Figure 1 is a plan. Fig. 2 isa detail, being a section through the upper part of the machine, takenat line 2 2 of Fig. 1. Fig. 3 is a vertical longitudinal centralsection. Fig. 4 is a detail, being a front view of the plate whichreceives the punches or pins and some other parts. Fig. 5 is a detailshowing the arrangement of the perforating-pins. Fig. 6 is a sideelevation showing two of the perforatingpins and bars to which they areattached. Fig.7 is a detail,being a side elevation of one of the slidingbars which act upon the crossbars, which are secured to the sliding barswhich carry pins.

This invention relates to apparatus for perforating paper in automatictelegraphing; and the objects of the invention are to improve the priormechanism and to provide novel means whereby the single depression ofone key will produce the dots, dashes, and spaces required for any oneletter.

To accomplish these objects my invention involves the features ofconstruction, the combination or arrangement of devices, and theprinciples of operation hereinafter described and claimed.

In the drawings, 1 indicates a base; 2, a narrow front piece; 3, a rearpiece, which forms part of the frame, and 4 a top piece, the center ofwhich is cut out, which forms the upper part of the frame, and issupported by the rear piece 3 and by two posts, one of which 5 is shownin Fig. 3, the other post being at the right-hand of the machine. Screws6 pass through the part 4 into the posts 5.

7 are a number of keys or levers, of which, as shown, there aretwenty-four. Each lever is provided with afinger-piece 8, each of whichis used for a letter, except that the letter J is made by repeating theletter N, and the letter L is made by combining the letters I and M. Ihave indicated on these keys the arrangement of the letters which Isuppose to be the most advantageous. Each keyor lever 7 extends back, asshown, on a diagonal line to the rear of the machine, and is therepivoted on a rod 9, which is supported in the frame, and from there eachkey or lever extends up vertically, and each vertical part 10 is pivotedat its upper end 11 to a sliding bar 12, which sliding bars 12 are allsupported in cross-bars 13 and 14, which are secured to the upper partof the frame. Each of these sliding bars 12 is provided with one or morelugs 15, for the purpose of operating the punch rods or pins, ashereinafter more fully described.

16 are four bars, each one of which carries at its forward end a punchrod or pin 17 18 19 20. These bars 16 are supported by and slide in across-bar 21 and a guide 22.

23 are four shorter bars under the forward ends of the bars 16, each ofwhich carries at its forward end a punch rod or pin 24 25 26 27. 28 isanother sliding bar at one side of the bars 23, and this bar carries apunch rod or pin 29. All of these bars 23 and 28 are supported by andslide in the cross-bar 21.

3O 31 32 33- 34 are cross-bars, one of which is permanently secured toeach one of the sliding bars 23 and 28, and 35 36 37 38 are four othercross-bars, one of which is secured to each one of the sliding bars 16.The ends of these bars 30 to 38 are recessed, and are arranged in slidesand guides 39, which are provided with partitions 40.

41 are springs arranged to act upon the ends of the cross-bars 30 to 38and return them to their normal position after they have been 7 forcedforward.

42 is a block through which the pins 17, 24,

.and 29 pass loosely. Each of these pins is provided with a fixed collar66, arranged to come in contact with the back side of the block 42.

43 is a punch rod or pin, which is permanently secured to the block 42.

44 are springs, which encircle rods which are permanently secured to theplate 47 ,which springs act upon the block 42 and return it to itsnormal position after it has been moved forward.

45 is a bracket secured to the frame.

46 is a plate secured to the bracket 45,which plate is provided withholes to receive the punch rods or pins.

IOC

47 is a plate secured by screws to the plate 46, washers being placedbetween the two plates to provide a space for the passage of thepaper tobe operated upon.

All of the punch-pins pass through a plate 64, which is supported by theframe, and in their normal position their forward ends enter the plate47.

48 is a rock-shaft, the ends of which are pivoted in the posts 5.

49 are arms rigidly secured to the rockshaft 48.

50 is a cross-bar suspended from the arms 49 by the rods 51. Each lever7 is provided with a notch on its under side to receive the cross-bar50, and the depths of the notches in these levers 7 vary.

52 is a cylinder supported in brackets 53. There are two of thesecylinders-one on each side of the center of the machine.

54 are short cylinders provided with heads at each end, which cylindersenter the cylinders 52 a short distance.

55 is a spring located in the cylinder 52, arranged to act upon one ofthe cylinders 54. There is a similar spring in the other cylinder 52.

56 are arms secured at their lower ends to the rock-shaft 48. Theirupper ends are arranged to engage with the outer heads of the cylinders54.

57 are two feed-wheels, which are provided with sharp teeth, for thepurpose of feeding the strip of paper through the machine.

58 are two wheels, each provided with a rubber surface, between whichwheels 57 and 58 the paper passes.

59 are pawls pivoted one to the front end of each of the short cylinders54. These pawls engage with ratchet-wheels on the lower ends of theshafts which carry the wheels 57, which shafts are supported in longbearings 60, which are supported by the bracket 45.

61 is a bar supported by two levers 62, which levers 62 extend back toand are pivoted upon the shaft 9. These arms or levers 62 are alsoprovided with notches to engage with the bar 50.

63 is a spring, one of which is provided for each of the levers 7 andfor the bars or levers 62.

The operation is as follows: To indicate a dot at the beginning of aletter requires the pins 43 and 29. To indicate a dash at the beginningof a letter requires the pins 43 and 24. Thus the pin 43 must be used atthe beginning of every letter. If the pin 29 be pushed forward, it willcarry with it the pin 43, because the collar on 29 will cause the block42 to move, and the pin 43 is fast to this block, and these two pinsbeing one over the other perforations made by them will indicate a dot.If the pin 24 be moved forward, it will carry the block 42 along, thepin 43 moving with it, and the pins 43 and 24 being diagonal with eachother their perforations will indicate a dash. Each of the bars 12 isoperated by one of the keys 7, and each bar 12 is to be provided withlugs 15, sufficient in number and properly arranged to operate the pinsbrought-into use in making the perforations required for the letter tobe indicated. For example, F requires a dot, a dash, and a dot, and thenthere must be a space after the last dotto show that the letter has beencompleted. Therefore when the F-key is struck, the pins 43 and 29 toindicate a dot, the pins 17 and 25 to indicate a dash, and the pins 19and 26 to indicate another dot, must all be operated simultaneously, andthen the paper must be moved beyond the pins, so as to leave a spaceafter the perforations. To do this the proper bar 12 must be providedwith lugs to act on the bars 30, 35, and 32, 37 and 33 at the same time,and then all the perforations required for the letter F will be made,because the bars last mentioned are connected with the sliding bars,which carry the pins to be operated. After these perforations have beenmade the paper must be moved far enough to carry all thelast-madeperforations beyond the pins and provide a space. The paper is moved bythe pawls 59 and wheels 57, and the distance the paper moves isdetermined by the depth of the notch in the lever which is operated.When one of the levers 7 descends, the shaft 48 will be rocked throughthe rods 51 and arms 49, and the arms 56 will force the cylinders orplungers 54 into the cylinders 52, which will carry the pawls 59 back,the distance which they are moved depend ing on the distance which thelever descends. When the lever is released, the springs in the cylinders52 will act on the cylinders or plungers 54, forcing them forward withthe pawls 59, which, being engaged with the ratchet-wheels 65, willcause the wheels 57 to rotate, carrying the paper along the properdistance. The pointed teeth on the wheels 57 will engage with the rubberon the wheels 58. A double space can be provided for at the end of eachword by depressing the bar 61, and the arms or levers 62 will engagewith the bar 50, rocking the shaft 48, and causing the plungers 54 toenter the cylinders 52, and when the spacing-bar 61 is released theaction of the springs in the cylinders 52 will cause the pawls tooperate upon the ratchet-wheels, as before, moving them one notch. Ihave not provided any keys for the letters .1 and L. To make theperforations for the letter J, the space-bar 61 is to be held down. Thenperforations for the letter N are to be made twice. Then the space-bar61 is to be released, and the paper will be moved the proper distance.To make the letter L, the space-bar 61 is to be held down. Theperforations for the letterI are to be first made and followedimmediately by the perforations for the letter M. Then by releasing thespace-bar 61 the paper will be moved the proper distance. By-the use ofthe space-bar alone the feed-wheels will be moved one notch. Whenperforations, are

made which indicate dots, the feed-wheels will be moved two notches Whenperforations are made which indicate dashes, the feedwheels will bemoved three notches.

A full-sized machine may be about ten inches long, about three incheswide at the back, eight inches in front, and about four inches high. Theparts are to be made of metal, and must all be made strong and of goodworkmanship, the best of steel being used for the working parts.

1. In a perforating-machine for automatic telegraphing, the combinationof a series of movable perforating-pins for punching parallel rows ofperforations, pin-operating devices, a series of keys for actuating thepinoperating devices, and each of which in its movement advances two ormore of the perforating-pins, a rotating wheel having teeth to punch acenter line of perforations, and means for rotating the wheel by themovement of the keys, substantially as described.
